用了亚马逊免费的EC2以后，因为没什么经验，所以每天都要看几次账单，看看到底怎样会被扣费。
起初，因为数据传输，可能是因为数据库外连了，所以看流量和费用都正常，0.02 USD，尚可以接受，起码知道怎么回事。
但是周五晚上，27日凌晨，忽然发现异常的费用产生，而且不断在增长，区域是Oregon，但是这个区域的EC2早已在月初删掉，而且费用的名目是通用存储，我在这个区域压根没有任何东西了，怎么可能占用存储，还持续增长呢？我反复检查了几个小时，确认没有任何存储的东西，但是费用依然在涨，无奈了，提交ticket，讲明我在这个区域早已没有使用任何服务，为什么会产生费用？而且不断增长。
超过12小时没回应，没办法啊，我只能关闭账号，关闭以后发现仍然在增长，我直接晕了，为了避免无辜损失，我把信用卡的授信额度直接设为0，耍赖我还是会的。
然后今天凌晨才给我回邮件，大概意思是说，这是他们的一个错误，已经进行修复。nnd
刚才看了一下，账户的费用终于还原正常了：
他们回复的工单内容：
